摘　　要：针对电网波动性导致输电网规划经济性降低的背景,基于两类需求响应用户自身运行特性和目标,以分时电价的激励形式,建立了考虑空间差异性的双层输电网扩展规划模型。上层以线路规划成本和需求响应成本之和最小为目标,建立了混合整数线性规划(mixed integer linear program,MILP)的输电网扩展规划模型,下层考虑电采暖用户和大工业用户的差异化运行约束,建立了以用电费用最小为目标的需求响应模型。根据库恩-塔克(KKT)条件将下层模型转换为上层模型的约束条件,采用Big-M法对非线性问题线性化。最后,基于IEEE 24节点仿真系统分析验证所提双层规划模型的有效性。最终决策出的电价方案可以体现需求响应资源的空间差异化价值,有效降低电网规划的成本,实现电网和参与需求响应用户的互利共赢。The volatility of power grid leads to a decrease in the economical transmission network planning.Based on the operating characteristics and goals of two types of demand response users,we establish a dual-layer transmission network expansion planning model considering spatial differences in the form of time-of-use electricity price incentives.The upper layer establishes a MILP-based transmission network expansion planning model with the goal of minimizing the sum of the line planning cost and the demand response cost.Considering the differentiated operational constraints of electric heating users and large industrial users,the lower layer establishes a demand response model with the goal of minimum electricity cost.We use the KKT conditions to transform the lower layer model into the constraints of the upper model,and utilize the Big-M method to linearize the nonlinear problem.Finally,we verify the validity of the proposed dual-layer planning model based on the"IEEE 24-node"simulation system.The final electricity pricing scheme can reflect the spatially differentiated value of demand response resources,effectively reduce the cost of grid planning,and achieve mutual benefit and win-win outcome for both grid and users participating in demand response.
